Subject:      Oil pressure light comes on after about 7 minutes.
Content-Type: text/plain; charset=ISO-8859-1

Hello folks,

Very odd, the oil pressure light comes on after about 7 minutes of driving. 1989, 2.1 WBX. It happens every time. If I let it sit, and get half-way cool, then it takes about 2-3 minutes for the pressure light/buzzer to come on. I think the timing is associated with the oil warming up. This has never happened before. I recently did an oil change, so maybe... And I have been doing some studying in the archives. So, I had bought one of those package deals at Autozone, you know for about $0.43 you get 5 quarts of oil and a filter.

So, first, I took some oil out, it was near the high mark (in the past I have suffered the oil pressure light on long uphills, so I am familiar with this problem). The oil level is now close to the minimum mark. Problem remained.

So it was a Bosch filter, and in the archives this oil filter is questionable. So today I replaced it with a Napa Gold, which is really a Wix, which was recommended, and the problem remains.

The oil is still golden in color and clear,no sign of chocolate mousse or contamination.

When I go downhill, at idle in neutral, the light/buzzer go out after about 7-10 seconds.

The next step I am considering is to get some different oil. I know I am being a bad vanagon owner, but I can't even recall what oil or weight I used, pretty sure it was 40W or close to that. Probably Castrol or Pennzoil, just can't recall. So I am thinking of putting some 20W-50 in. Am in San Diego, really never drive it below 40 degrees, but this is not a high temp / high stress problem, we are in the 50s-60s each day.

I think I have a "frothing oil" problem of some type. Another post said that "Castrol GTX 20w-50 is only $13 for 5 quarts at Wally World", maybe not anymore, but I haven't been there is a while.

Any comments? Thank you!

Roland
